Comparison of the clinical performances of Air-Qsp and i-Gel for airway management under general anesthesia with a muscle relaxant.

Study Objectives: Recently, i-Gel intubating laryngeal airway (ILA) has been frequently used because of the ease for airway insertion by residents and young anesthesiologists. However, it sometimes fails to fit or ventilate sufficiently in Japanese patients. Use of Air-Qsp, which is a new non-inflatable cuffed ILA, in a clinical setting has become possible.

[A case report of coronary artery fistula in which perioperative transthoracic and transesophageal echocardiography was useful for surgical decision].

Coronary artery fistula is rare in congenital heart diseases but is the major disease among "coronary" congenital diseases. In a coronary artery fistula, the coronary artery tip connects directly or via an unusual blood vessel to unusual parts, such as the inside of the heart chamber, pulmonary artery or superior vena cava. Left ventricular volume overload and coronary steal phenomenon are serious symptoms.
